Topic: 2009 G5 Muffler (Read 1615 times)

2009 G5 UCE EFI Muffler and header pipe discolored after 2200 miles. Is this a problem with the muffler or pipe or just a normal occurance? The Header I can understand but the muffler? I realize there is a converter in it and that it will get hot but to discolor this much in a short time? It looks almost like it is rusting on the outside of the chrome. Possible warranty issue? Any help is appreciated...

I have about 2100 miles on my G5 and I have the blueing on the header and some on the muffler under the heat shield but not any behind the heat shield like yours. Yeah, that doesn't seem right and looks like shit. Hopefully they will replace the muffler.

I think the heat sheild is there to prevent you from being burnt by preventing the heat from the exhaust from disipating into your leg. Is it possible that this causes the other parts of the pipe to become hotter than normal as this surplus heat has to go somewhere?

Does the heat sheild cover any joints in the pipe? If these joints are not sealed properly then escaping gases could also cause discolouration.

On a kind of related note; Do all the new pipes with the Cat. Converter in them look like they have been stock chromed pipes that were cut open at the front and re-welded and then painted over the welds and chrome? The one we have now looks kind of cheesy to me in that aspect.

Those UCE/EFI front pipes and mufflers were always going to get hotter than hot.

If you have a faired in plastic rocket type bike then you won't worry that the system has gone all colours of the rainbow. As Ace says, the answer for Bullet style everything-on-view bikes is double walled pipes.

Suppose you could by new pipes and have them sent out to be ceramic lined to help dissipate the heat, that would also cure the problem forever. But double wall is the best solution. The Vance and Hines on my Kawasaki Drifter haven't turned blue in almost 10,000 miles. Will.
